Behind the scenes
The Golden Lagoon of White Agony Plains, the 15th episode of DuckTales 2017, was released on the 23d of June, 2018.
According to Francisco Angones on Frank Angones and the Suspenders of Disbelief, it is possible that Goldie used a magical time-speeding artifact akin to a Time-Teaser to accomplish some of her feats at the start. He also stated that the reason Goldie didn't come across Duckworth when raiding McDuck Manor was that he was dusting another part of the house.
